## ARTICLE:

Kenya's construction industry is navigating a critical inflection point. The government's import levy on cement clinker—introduced as a domestic industry protection measure—has coincided with an unexpected surge in demand, as the sector recorded an 82% increase in clinker tonnage through 2025. This paradoxical recovery reveals both resilience and tension within Africa's third-largest construction market.

### What is driving Kenya's clinker import surge despite the new levy?

The construction sector's rebound reflects pent-up demand from the 2023–2024 economic slowdown and infrastructure acceleration under the newly implemented five-year National Development Plan. Major projects—including the Standard Gauge Railway phase II expansion, affordable housing initiatives, and commercial real estate in Nairobi, Mombasa, and emerging tech hubs—have reignited cement consumption. The 82% tonnage growth suggests that even with tariff pressures, the cost of *not* importing clinker (and thus failing to meet domestic demand) outweighs the duty burden.

Clinker, the calcined material at cement's core, represents 90% of cement's value and is typically imported for blending into finished product. Kenya's domestic clinker production capacity remains constrained—limited to Bamburi Cement and a handful of smaller mills—leaving importers dependent on regional suppliers (primarily Tanzania and Ethiopia) and international markets.

### How does the levy reshape project economics and contractor margins?

The import duty effectively raises clinker costs by 8–12%, depending on tariff structure and origin. For contractors operating on 3–8% net margins (typical for East African construction), this translates to compressed profitability unless prices can be passed to clients. Large-scale infrastructure projects (where government is the payor) absorb tariff costs more easily through budget adjustments; mid-market commercial developers face harder choices. Some contractors have accelerated procurement ahead of levy increases, while others have shifted to blended cement formulations using domestic additives—a strategy that reduces clinker intensity but requires technical recalibration.

The levy also creates competitive divergence: multinational cement producers with regional supply chains can distribute tariff burden across markets, while smaller domestic millers lack this flexibility and face margin squeeze.

### Why hasn't the levy stalled construction momentum?

Several factors sustain demand despite tariffs. First, Kenya's urbanization rate (4.2% annually) and middle-class growth create secular housing demand that tariffs cannot suppress. Second, infrastructure spending—especially transport and energy projects—is politically prioritized and budget-protected. Third, clinker imports have inelastic demand: cement is non-substitutable, and construction timelines cannot easily flex around price spikes. Finally, the 82% tonnage increase suggests that supply-side fear of the levy may have been overestimated; the duty rate, while meaningful, has not triggered the contraction some predicted.

**Market Outlook:** The construction sector's continued expansion despite tariff headwinds indicates strong fundamentals. However, sustainability depends on clinker supply stability and whether domestic producers can expand capacity to reduce import dependency—a multiyear capex play. Investors should monitor cement company earnings (Bamburi, East African Breweries' construction supply subsidiaries) for margin trends and watch for policy signals on further tariff escalation.
